Topic may be beaten to death but I want to know what the difference is between 10X aviars and current run 12X aviars? I have 10X aviars and know they are bulletproof but havent handled a 12X yet. I know the mold is the same but how about the plastic, stability, durability, etc.

You're coming from a different perspective than most people asking this question. Why not just go fondle a few 12x's? They are ubiquitous. It's hard to believe you haven't seen a 12x Aviar in the last 6 years or w/e.

Anyway...they're not as hard and feel a bit waxier, but they develop a little better grip after they get scuffed up.
